Overview
The ADM1060ARU-REEL7, produced by Analog Devices Inc., is a programmable supervisory/sequencing device designed to provide a single-chip solution for multiple power supply fault detection and sequencing in communications systems. This device is particularly useful in central offices, servers, and other infrastructure systems where multiple power supplies are required to power different sections of the board. The ADM1060 ensures that these supplies are sequenced correctly to avoid damage, miscommunication, or latch-up.
